Measurement System Quiz

The first stage in a generalized measurement system is:

• Conversion stage

• Sensing stage

• Recording stage

• Manipulation stage

The manipulation stage in a measurement system is used to:

• Convert the measured signal

• Amplify or filter the signal

• Record the measured data

• Sense the physical quantity

The output of the sensing stage is typically:

• An amplified signal

• A mechanical signal

• An electrical signal

• A readable display

The recording stage in a measurement system:

• Converts the signal to another form

• Amplifies the signal for clarity

• Stores data for analysis or future use

• Senses the input parameter

In a measurement system, the conversion stage primarily:

• Converts the sensed signal into an electrical form

• Measures the physical quantity directly

• Filters unwanted signals

• Records the data

Absolute instruments measure:

• Parameters without calibration

• Values with direct comparison to a standard

• Electrical signals only

• High-frequency signals

Secondary instruments require:

• No calibration

• Calibration against a standard

• Direct deflection reading

• No deflection mechanism

Analog instruments are characterized by:

• Continuous signals for display

• Discrete signals for display

• Binary output

• Digital processing

A null deflection instrument works by:

• Balancing the measured signal against a known value

• Deflecting a pointer proportionally to the signal

• Converting the signal to digital form

• Amplifying the input signal

A deflecting instrument provides measurement by:

• A balance mechanism

• A pointer moving on a scale

• Generating binary data

• Providing no visual indication
